Awarded by the Abdus Salam International Centre for Theoretical Physics "for pioneering contributions to the quest for a unified theory of quarks and leptons and of the strong, weak, and electromagnetic interactions." Shared with Howard Georgi and Jogesh Pati. "...The award to Quinn recognizes the Georgi-Quinn-Weinberg computation (showing that the natural mass scale of unification is relatively close to the Planck scale, and that the proton lifetime can naturally be extremely long), as well as her fundamental insights (with Peccei) about CP conservation by strong interactions."
